AMD's Dual-GPU Radeon HD 7990 is the "World's Fastest" Graphics Card

That's according to AMD, which used a presentation at the Game Developers Conference to give PC press a preview of a work-in-progress version of its forthcoming triple-fanned monster.

The Radeon HD 7990 contains two of the chip maker's 7990 series GPUs, with AMD product manager Devon Nekechuk claiming the card is "whisper quiet" and delivers "massive performance" for gamers who demand their characters have the most realistic hair possible. But he didn't say when it's likely to be delivered to shops and houses. Or how much it'll cost. [Techradar]
